fa: here's an interesting piece of technology you don't see too often - slide system with magnetic audio track on each slide

since some of you folks like interesting technological oddities, here's one for your collective amusement: I've had this thing sitting around for a very long time - much too long, it seems to me - but it's an interesting system - could be good for a club, or for showing off a collection - here's the link

've never seen another system like this, in fact this is the only one I've ever seen - I couldn't find much about it via a web search - some erroneous information from one other person trying to sell one for $179 on ebay (I started the auction at 99 cents - I wouldn't be too surprised to see it go for that price, but it's time for it to find a new home) -

So, guys, are any of you aware of other equivalent systems? or was this the only example of a combined audio and slide projector?

"Bill Noble" fired this volley in news:hs2nnc$a16$ snipped-for-privacy@news.eternal-september.org:

To the best of my knowlege, that's the only commercial system that actually carried the audio on the slide carriers. Just the fact that you were left to mount your own slides would have limited its popularity.

Hughes, Bell & Howell, Agfa, and others made audio-syncronized presentation projectors that used cassette tapes to drive the slide show. Audio was on one track, and "change tones" were on the other of a common

4-track stereo cassette deck.

I had a Bell & Howell Communicator when I worked in the insurance industry. It was a fold-up briefcase version of the above.

But audio ON the slide carrier? No. The closest parallel I can draw to that was the old Burroughs Mag Stripe Accounting Machines, that held the account balance info on a printed-on magnetic stripe on the side of an otherwise normal paper accounting leger card.
